Abstract: PURPOSE:To prevent generation of deformation or warp in a ceramic material due to calcination at high temp. by filling two kinds of ceramic powder having remarkably different specific gravity and coefft. of thermal expansion from each other into a porous sintered body consisting of a ceramic powder material and a fibrous ceramic material. CONSTITUTION:A porous body is formed by calcining a mixture consisting of ceramic powder (A) and a fibrous ceramic material after kneading the mixture and molding. Said porous body is then impregnated with an aq. slurry of two kinds of powdery ceramic material (B, C) having remarkably different specific gravity and coefft. of thermal expansion from each other. Thereafter, the impregnated product is calcined again. In this case, suitable fibrous ceramic material is wollastonite, etc., and suitable calcination temp. for obtg. the porous body is about 700 deg.C. Suitable two kinds of the ceramic powder (B, C) for filling are those having ca.1000 mesh particle size, and a combination of B and C wherein one expands at 700-800 deg.C and another contracts at the same temp. is desirable if possible. By this method an extremely thin ceramic plate having a large size is obtd.

Abstract: PURPOSE: To male the heights of solder bumps constant and to prevent gold plating from diffusing in the solder. CONSTITUTION: A connection member 10 is composed of a core 11 and a solder layer 12 which has a lower melting point than that of the core 11. The connection member 10 is placed on the cream solder 32 applied on a pad 31. The through hole 25 of a tape carrier 20 is positioned on the connection member 10. The through hole 25 is tapered and its inner side is gold plated. The connection member 10 and the cream solder 22 are heated and melted to be solder 13. The solder 13 enters inside the through hole 25. The core 11 is not melted and supports the tape carrier 20 on a mounting substrate 30. The heights of the solder bumps between the tape carrier 20 and the mounting substrate 30 are fixed by the presence of the core 11 in between.  Since the core 11 which does not contribute to gold wire occupies most of the volume of the solder bump, diffusion of gold applied on the pad 31 and a conductor pattern 23 is prevented.

Title: Method for preparing nc processing data of evaporative pattern for casting
Inventor: SAWADA KOJI
IPC: B22C7/02
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To NC process an evaporative pattern for a casting having a vertical face without non-ground portions and eliminate necessity of a manual operation, resulting in reduction of a manufacturing cost by adding a wall face cutting pass, wherein vertical parts at the middle of a scan cutting pass, are sequentially connected at the shortest distance to the scan cutting pass. SOLUTION: A non-connected divide cutting pass is sequentially detected from the first divide cutting pass. When the unconnected divide cutting pass exists, the divide cutting pass found at first is taken as a connection cutting pass. When a vertical part exists on the divide cutting pass, the vertical part is removed to form a new divide cutting pass, so as to memorize an end position of the divide cutting pass wherein the vertical part is removed. The end point of the connection cutting pass formed in advance and the start point of the next connection cutting pass are connected by a moving pass T which is relieved to a safe height. Wall face cutting passes W1, W2, W3, W4 for connecting the end point at the shortest distance are obtained, and added to scan cutting passes A1, A2, A3, A4, A5 so as to form a new connection cutting pass.

Abstract: PURPOSE:To remove metallic contaminant, a defect layer, etc., on a substrate surface and to prevent generation of a step and deterioration of breakdown strength in an edge part of an isolating selective oxide film by incorporating a specific amount of nitric acid and hydrofluoric acid and by making etching rate of single crystalline silicon to a silicon oxide film not exceeding a specified value. CONSTITUTION:This solution is composed of water solution containing at least nitric acid of 30 to 50% and hydrofluoric acid of 0.1 to 1.0% and having etching rate of single crystalline silicon to a silicon oxide film not exceeding 1.0. For example, relation between a concentration of HNO3 and HF in the cleaning solution and etching rate of single crystalline silicon to a silicon oxide film is as shown in the figure. When a concentration of HNO3 is not exceeding 30%, reaction rate is controlled by oxidation and a surface of an Si wafer is roughened. When it is 48% or more, etching rate of Si to SiO2 becomes too large. When a concentration of HF is 0.1% or less, etching rate is too large, and when it is 1% or more, reaction rate is controlled by the oxidation and a surface of the Si substrate is roughened.
